[1]} first proposed the idea of distant supervision or weak supervision to create a large text-tuple parallel training dataset for relation extraction. They mapped Freebase [2]} tuples to Wikipedia articles to obtain the dataset. [3]} and [4]} mapped Freebase tuples to the New York Times (NYT) articles to obtain another dataset. These two datasets are used extensively by researchers for their experiments. FewRel 2.0 [5]} is a few-shot relation extraction dataset. These datasets are created at the sentence level.
